Hi Folks,I have just installed a new hard drive and reloaded FS9 and while I copied the files from the backup (therefore no change in the settings) I've found a problem in the frame rates.While sitting stationary I get around 15 FPS but as soon as I move it drops to 1 or 2 FPS. It seems a bit strange but that didnt appear when flying a helicopter. I then worked out that the frame rate problem only existed while the aircraft was touching the ground, once airbourne the rate went back to 15 FPS.I never had this before on the other hard disk so anyone got any suggestions on sorting this one out? I've tried turning off the antivirus software with no change.Thanks ronAthlon 21001 Gig SDRAMATI 9200 video cardGigibyte motherboard with Via chipset

Try this:Go into FS display settings and move the "Terrain detail" slider to None.If you have a Force Feedback yoke or joystick, try running FS without it connected.

do i understand you correctly; you backed up the fs9 folder and then restored it later onto the new drive? or did you backup the whole drive windows and all? cheers, James

Hi,I backed up the FS9 directory. When I formatted the hard drive I installed FS9 then replaced all of that with the backup copy.Rgds Ron

Hi,I've tried all the variable settings with no change. It's strange that no matter what settings I used it's only when the aircraft is on the ground I get any problems. With a helicopter as it lifts off its not a problem because it comes off the ground but starting at the same spot with an aircraft its only OK once the wheels are off the ground. Put them back down and its slow again.Rgds Ron

Try deleting fs9.cfg and allowing FS9 to rip you...er, make you a new one?

Guess what...It didn't work.But thanks for the thought.Cheers Ron

Did you defragment the new hard drive after the copy? That might help.

Hi Craig,Yes, been through all the usual tricks. Even went back to square one and cleaned the drive, reinstalled windows followed by FS9. Defrag'd and checked it again with no change.Bit of a puzzle this one but I've just found another thread with another simmer having the same unexplained problem. Don't think he found a result yet either.Rgds Ron

right ok well, maybe you should try uninstalling the sim, then reinstalling it, see if the problem persists with a clean install, if its fine then you know its the older installation.....

Hi James,I've tried that twice today. Stupid thing it that on the old hard disk it worked OK but it doesnt seem right thats a change of hard drive (from 60G split into two partitions to a single drive of 80G) should change anything at all.I've been trying all sorts of things and changing all sorts of settings both in FS9 and windows XP and getting no change to this very annoying problem.Makes me almost tempted to go back to Windows 98 and really start all over again for the third time today. (Didn't help in that XP would not reactivate saying I had exceded number of tries although a phone call sort that out.Rgds Ron

hi,this may sound stupid but have you changed the resolution to see if that helps? or have antialiasing /anisotropic filtering become turned on? and have you tried the sim in different locations like somewhere less busy? The Bahamas for instance i know that MYAK is nice this time of year :) i also take it that the directX and other drivers are the newest versions?A couple of times when i was about to taxi and throttle up, it went jerky then smooth when i powered back down, only happend on land as well. It has actually stopped doing it now and it was nowhere near as bad as your problem but it may be loosly affiliated, maybe it will sort itself out :)cheers,James

Not sure if this is related to what you're experiencing but I had to reformat my hardrive this week, after reinstalling everything I've noticed that my frame rates are way down in FS9. I've downloaded all the same drivers as before, but no improvement. I went to the local computer store and while talking with the tech I mentioned that before the reformat, I was using FAT32 but when I installed Windows XP, I set it up as NTFS (I think that's it), he said it was very possible that was the problem. Tomorrow, I reformat using using FAT32.... I'll let ya know if it works.Good LuckDave

BINGOProblem sorted.It was the force feedback on the microsoft joystick. Turned it off and the problem disappeared. It also increased the frame rate from 15FPS to the limit I set of 20 (so it might even be better than that!)Now you would have thought Microsoft would make sure there own games (sorry simulations) worked with there own hardware, well OK perhaps not.Thanks for all the thoughts and sugestions.Rgds Ron

thats good that you have found out but i could not lose the force feedback anymore, i was unsure at the start but now its the best. anyhow i would reccomend writing to ms to see if theres a solution. cheers,James
